HINGE.

Application led May 21, 1923. Serial No.`640,558.

This invention relates to hinges, and more particularly to theconstruction and arrangement of hinges and their associated parts forinwardly swinging sashes.

One of the objectsof the invention is the provision of new and improvedhinge mechanism for connecting a stationary and hinged member together,whereby the hinged member will be supported durinfr its rotation inopening the same and will be effectively wedged or clamped against thestationary member in closed position for eEect-ing a water and weatherproof joint between said members.

Another object of the invention is the emf ployment of new and improvedhinge mechanism for connecting a window frame and its sash in such amanner that a water and weather roof joint is effected when the sash isclosedl? and will automatically lock the sash when the same is moved toopen position.

Still further objects of the invention are the provision of a new andimproved. hinge that is cheap to manufacture, easily assembled,efficient in operation, adjustable and not likely to get out of order.

Otherand further objects of the. invention will appear from thefollowing description, taken in connection with the accompanyingdrawings, in which- I Fig. 1 is a front elevation of`a portion of awindow frame and 'its sash, with the invention in position thereon,parts broken away;

Fig. 2 is a vertical section on line 2-2 of Fig. 1 showing the window inopen position, parts broken away; y

Fig. 3 is a view similar to Fig. 2, showing the window in closedposition;

Fig. 4 is a perspective of a portion of the window sash showing onemember of the hinge attached thereto;

Fig. 5 lis a detailed view of onemember of the hinge, the other memberof the hinge and portion 'of the sash being shown in dotted'lines; and lFig. 6 is a planview of both members oi the hinge, showing the same in.assembled relation.y

It is understood that the hinve may be employed in various relations,but for simplicity of illustration and convenience` of descri tion thesame is shown and will bedescri ed as applied to a window frame and itsinwardly swinging sash, such for instance as as by are employed in'basements and attics of dwellings, shops, stores and the like.

It is understood, however, that the hinge may be employed on closuresland the like opening outwardly, and that the terms indieating directionare yrelative terms employed for convenience in describing theinvention.

On the drawing the reference character 10 designates a window casing orframe which may be of the usual construction. The frame is provided witha stop member l1 which is in the form of an inverted U andl extendsacross the top and down the sides of the inner periphery of the frame10. A ledge 12 is secured to the inner surface of the lower portion ofthe frame 10, in spaced relation to the stop 11. Window sash 13 isadaptedv to have its lower edge extend lbetween the stop 11'and ledge 12when the same is in position to close the opening formed by the stopmember 11 and the bottom wall of the casing or frame 10. I

-Suitable means are provided for hinging the sash to the frame in such amanner that when in the closed position shown in Fig. 3 the sash will besupported in such a manner that it will be wedged against the stops 11and the lower portion of the sash will be located between the stop andledge 12.

The hinge member for accomplishing this function will now be described.For convenience of description the hinge member 14 for connecting Ithesash 13 tothe frame 10 will be descrlbed as it appears in Fig. 3.-

l The direction toward. the left of the drawing will be referred to asuinwardly 'and toward the top of the drawing as upwardly. The hinge 14com rises the member 15 which will be termed t e fixed member and themember 16 which will be termed the movable member. The hinge member 14maybe formed in any suitable manner, but preferabl it is stamped fromsheet metal which ma es' a construction that isl easily, and cheaplymanufactured. p

The fixed member 15 is adapted to be secured to the sash 10 inanysuitable manner, means of nails or screws. This member isprovided withan angular slot 17 (see 5) having its apex-extendin inwardly an havingone portion 18 exten ing down wardly and outwardly and its other portion19 extending upwardly and outwardly, from said apex. y

The movable member 16 of .the hinge is provided with an attaching footor base 20 which is provided with slots 21 for the reception ofattaching screws 22 whereby the said member may be adjusted verticallyon the sash 18. The body portion 23 extends inwardly at right angles tothev attaching portion 2O and is provided with a pintle or pivot member24 for engaging in the slot 17 of the fixed member 15; Its inner end isbeveled off or shaped to form a camming surface 25, for a purposethatwill presently appear.

The lower edge of the body portion 23 is provided with notches or teeth26 which are adapted to engage a stop or rigid latching member 26a forholding the window in adjusted position. The stop or latch member 26amay be rigidly secured to the window frame in any suitable manner;preferably the same is formed by bending the inwardly extending portionof the plate 15 at right angles to said plate. The notches or teeth 26are arranged on the arc of a circle about the pivot pin 24 as a center.

The parts are so arranged that the distance between the vouter edges ofthe teeth and the pin 24 is greater than the distance between the apexof the slot 17 and the stop or latch 26a whereby it will be necessary tomove the pin 24 into the portion 19 of the slot 17 before the window canbe turned to its open position.

If desired, the pintle 24 may be provided with a head 24a for engagingthe outer face of the plate 15, a groove being made in the frame 10 foraccommodating the movement of the head. It is understood, however, thatthe head is not necessary to the operation of the device and may beomitted altogether.

The parts are so arranged that when the sash is in the closed positionas shown in Fig. 3 the pintle 24 riding in the inclined portion 18 ofthe slot 17 will tend to force or wedge the window against the stopmember 11. The slots 21 4permit the member 16 of the hinge to be soadjusted that the sash is supported independently of the lower portionof the frame. In other words, the weight of the sash is utilized at alltimes for wedging the same against the stop member 11. This isconsidered an important featurel of applicants construction because itprovides means for automatically wedging the sash against the stop eventhough the same should shrink during the extremely dry seasons of theyear.

In moving the sash from the closed position shown in Fig. 3 to the openposition, the same is first raised, causing the pintle 24 to rideupwardly in the slot 17 into the portion 19 thereof. The camming surface25 engaging the stop 26a will assist in directing the pintle into theportion 19 of the slot,.after whichthe slash may be rotated 'to thedesired position. After the camming Asurface 25 comes inl contact withthe stop 26a and the pintle 24 engages the portion 19 of the slot thewindow will be supported by the hinge during the further openingmovement of the sash. The notches, being arrangedl on the are of acircle, will ride past the stop 26a and the downwardly inclined positionof the portion 19 of the slot will cause the sash to tend to moveinwardly, thereby insuring the automatic engagement of the teeth 26 withthe stop 26L at any open position of the sash. In closing the sash, thevhinge members will support the same with the pintles in the portions 19of the slots until the sash is moved outwardly beyond the ledge 12 atwhich posi tion the cam surface 25 will become disengaged from the stops26n to permit the weight of the sash to Vcause the pintles 24 to slideinto and along the. portions 18 of the slots, thereby permitting adownward and outward movement of the sash to wedge the same against thestop 11.

- The stop engaging surfaces 27 of the teeth 26 may, if desired, bearranged at such an angle to the radii of the curve on which the teethare formed that a suiiicient pressure on the outer end of the sash willcause the same to become disengaged from the stop member.

f, It is thought from the foregoing taken in connection with theaccompanying drawings that the construction and operation of my devicewill be apparent to those skilled in the art, and that various changesin size, shape, proportion and details of construction may bemadewithout departing from the spirit and scope of the appended claims.
